   Hi Ilya.

> qcc also have "template-depth".

   I looked at this toolset and it seems to pass this parameter to the 
compiler in the following format:

   -Wc,-ftemplate-depth-100

   As I do not have access to this compiler or its documentation I do 
not really know how to interpret or change this setting so I have a few 
questions:

   What does the -Wc part stand for?

   Is this just one setting or two?

   If someone removes the template-depth property, should the -Wc 
parameter be left on the command line? Or should it be removed as well?

   Should this perhaps be changed to: '-Wc -ftemplate-depth-100' ?

   Without this information the best I can do is introduce a 
TEMPLATE_DEPTH flag for this compiler as done in the gcc toolset instead 
of integrating this option into the OPTIONS flag.

   Note that this toolset does not appear to have any precompiled header 
support so there no problem with the compile.c++.pch action like there 
is in the gcc toolset.

   I'll be posting an updated patch shortly. Just need to test it a bit 
first...

   Best regards,
